To make it easy.. We have a 12 gal tank. Add 3.5gal of E85, then fill it up with 93oct or 91oct.
There are places in the US you can buy E30, its just not E30 you'd want.
Also. I PM'd Randy about testing for him and he acted like i wanted him to tune for me for free. Like I was only doing it to get his tune without buying the AP from Mountune. I bought my AP from FSworkz or whatever back in Dec because they were the first ones to sell it. I still am not sure if i can even use Randy's tune IF I PAID FOR IT... I gave up anyway, I'm just going to buy access tuner and do it myself, lol
